PLEASE HELP WILL MARK BRAILIEST!!! A chemist reacts H2 with excess N2. The reaction yields 50 grams of NH3. However, you calculate you should have recovered 64 grams of NH3. What is the percent yield of the reaction? (Give two significant figures)

Percent Yield = % (Give two significant figures. For example, 2.2 has two significant figures)

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.

elements make up everything, and they combine to make compounds.

the answer is c

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
